From 4af87a939ef7092fdca267fba473cf8407d6d8e2 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Wed, 14 Mar 2012 19:48:43 +0000 Subject: [PATCH] ALSA: pcm: Constify the list in snd_pcm_hw_constraint_list Allows the constraint lists to be declared const by drivers which seems reasonable; there's plenty of other constification we could do if we were being complete but this was easy and quick.
